1.1/1.1 T2 ETP Tin Coated Used For Miscellaneous cans tea caddy
1. Introduction
• What is tinplate?
• Tinned steel sheet referred to as tinplate, commonly known as tinplate, is a product made of tinning on a thin mild steel plate. The tin plate produced by the hot dip process is called the hot dip tin plate, and the tin plate produced by the electroplating process is called the electroplated tin plate.
• Because about 98~99.8% of the weight of the tin plate is steel, it is a coated steel variety that belongs to metallurgical products.
Material Grades and Variants
The base steel of tinplate can vary based on its strength and thickness, but the tin coating also comes in different weights and compositions. These variations allow for different types of tinplate products based on the needs of the application.
1. Tin-Free Steel (TFS) / Electrolytic Chromium Coated Steel (ECCS):
- Instead of tin, this variant is coated with a thin layer of chromium and chromium oxide. TFS provides similar corrosion protection but at a lower cost. It is more commonly used in non-food packaging applications like paint cans or aerosol containers.
2. Single Reduced vs. Double Reduced Tinplate:
- Single Reduced Tinplate (SR): This type is cold-rolled once and is generally used for applications requiring more ductility, such as beverage cans or aerosol containers.
- Double Reduced Tinplate (DR): This type is cold-rolled twice, resulting in greater strength and a thinner profile, often used for lightweight food cans or lids.
1. Three-piece pop-top can for food and beverage:
- Market Status: This segment of the tinplate market is well-established (mature ETP market).
- Representative Clients: Includes prominent brands such as Wanglaoji, Redbull, and Robust.
2. Food can:
- Market Potential: Identified as one of the most promising segments for tinplate (ETP market).
- Usage: Tinplate is extensively used for packaging various canned foods, exemplified by brands like Huangguan, Meilin, and Gulong.
3. Screw cap and crown-shaped cap:
- Market Segmentation: ETP is specifically tailored for different types of beer packaging.
- Dominance: It serves as a primary supplier for crown-shaped caps.
4. Spray can:
- Market Development: This segment within the tinplate market is still evolving and offers significant growth potential.
- Usage: Tinplate is employed in the packaging of spray cans, with room for further expansion.
5. High-grade chemical can:
- Market Focus: Chemical-grade tinplate is dedicated to packaging high-quality paint materials.
- Application: It ensures the safe and efficient containment of chemicals used in paints.
6. Drawn can and DRD can:
- Emerging Market: A rapidly growing segment within the tinplate industry.
- Application: Primarily used for gift cans and other decorative purposes, indicating its rising popularity and application diversity.

The hardness is the average value of 2 samples, allowing 1 of them to exceed the specified allowable range by 1 unit. | |||||
a The yield strength is a reference value determined as required. b Yield strength is the average value of the two samples. The sample is P5 in GB/T 228, and the direction of the sample is transverse. c Due to the thickness thinning effect, the elongation is too low and the yield strength cannot be measured. In this case, the yield strength is replaced by the tensile strength. d For the tensile test, the width of the parallel part of the sample is (12.5±1) mm, and the standard distance L0=50mm. Before the test. The sample should be artificially aged for 20min at 200℃. |

Remarks | The internal control is set at-0.002mm of the thickness of the contract order. The measurement value of the midpoint in the width direction of the strip shall prevail. | The internal control sets the thickness of the contract order thickness. The measurement value of the midpoint in the width direction of the strip shall prevail. | The internal control is to set the thickness of the contract order at +0.003mm, and the measured value at the midpoint of the strip width direction shall prevail. |
1. The thickness of S1, S2, S3 surface and M surface shall be measured by the flat thickness meter. (The matt surface will be higher than the actual measurement due to surface roughness.) |
Bending, rolling
Thanks to its high level of ductility (for steel with low mechanical properties) and near-isotropic properties, tinplate can withstand severe bending or rolling.
Expansion, embossing, beading
Tinplate is well suited to mechanical, pneumatic or hydraulic expansion. Its expansion capacity by pneumatic or hydraulic means can be up to 30%.
